Radiator Cover Sizes Guide (Ireland)

Choosing the correct radiator cover size is one of the most important steps when buying a radiator cover.

A radiator cover that is too small may not fit properly over your radiator, while a cover that is too large can look out of proportion within a room. The good news is that most Irish homes use a relatively small number of common radiator sizes, making it easier to find a suitable option.

This guide explains the most common radiator cover sizes available in Ireland, how they are typically used throughout the home, and how to choose the right size for your radiator.

Standard Radiator Cover Sizes in Ireland

Most radiator covers sold in Ireland fall into four main size categories: small, medium, large and extra large.

Small Radiator Covers

Small radiator covers are typically between 78cm and 90cm wide and are commonly used in hallways, landings, box rooms and smaller bedrooms.

They are a popular choice in Irish homes where space is limited and where homeowners want to improve the appearance of a radiator without making the room feel crowded. Small radiator covers can also provide a useful shelf for keys, photographs and decorative items in entrance halls.

Medium Radiator Covers

Medium radiator covers generally range from 100cm to 120cm wide and are among the most common sizes found in Irish homes.

They are often used in bedrooms, dining rooms, home offices and family rooms where a standard-sized radiator requires a balanced and practical cover. Medium radiator covers offer a good combination of style and functionality while still providing useful shelf space.

Large Radiator Covers

Large radiator covers typically range from 120cm to 152cm wide and are often used in living rooms, larger bedrooms and open-plan living spaces.

Many homeowners choose large radiator covers when renovating a room because they help create a more finished appearance while disguising older radiators. The wider shelf space also makes them ideal for displaying photographs, plants and decorative accessories.

Extra Large Radiator Covers

Extra large radiator covers are generally used for radiators measuring over 152cm wide.

These are commonly found in larger living rooms, period properties, bay window areas and open-plan kitchen-living spaces. In many cases, an extra large radiator cover becomes a feature within the room while still allowing effective heat circulation.

What Size Radiator Cover Do I Need?

The best way to determine the correct radiator cover size is to measure your radiator before ordering.

Start by measuring the full width of the radiator, including any end caps and valves. Next, measure the height from floor level to the highest point of the radiator. Finally, measure the depth from the wall to the furthest point of the radiator.

As a general rule, your radiator cover should be slightly larger than the radiator itself. This allows the cover to fit comfortably while providing adequate airflow around the radiator.

If you have not yet measured your radiator, we recommend reading our How to Measure Radiator Covers Guide before placing an order.

General Size Guide

Radiator Width	Recommended Cover Size
70cm – 80cm	Small
80cm – 100cm	Small or Medium
100cm – 120cm	Medium
120cm – 150cm	Large
150cm+	Extra Large

These measurements are intended as a general guide. Always check the dimensions of the specific radiator cover before ordering.

Adjustable Radiator Covers

Adjustable radiator covers are an excellent option when your radiator falls between standard sizes or when you are unsure which size will provide the best fit.

Many older Irish homes have radiators that do not match standard modern dimensions exactly. In these situations, an adjustable radiator cover can provide additional flexibility while still maintaining a clean, fitted appearance.

Adjustable radiator covers are particularly popular in hallways, older properties and homes where radiators have been replaced or upgraded over time.

Choosing a Radiator Cover by Room

Different rooms often require different radiator cover sizes and styles.

Hallway Radiator Covers

Hallway radiators are often smaller and narrower than those found elsewhere in the home. A compact radiator cover can help create a tidy entrance area while providing useful shelf space for keys, photographs and decorative accessories.

Living Room Radiator Covers

Living room radiators are typically larger and are often positioned in prominent locations. Large radiator covers are popular because they help create a more polished appearance while providing a useful display surface.

Bedroom Radiator Covers

Bedroom radiator covers vary depending on room size, but medium-sized covers are often the most common choice. Many homeowners choose simple white or oak finishes that complement existing furniture.

Apartment and Small Space Radiator Covers

In apartments and smaller homes, space is often at a premium. Compact radiator covers can improve the appearance of a room without making it feel cluttered or overcrowded.

Common Radiator Cover Sizing Mistakes

One of the most common mistakes homeowners make is measuring only the radiator panel and forgetting about valves, pipework and end caps. This can result in a radiator cover that is too small to fit correctly.

Another common issue is choosing a cover that leaves very little clearance around the radiator. A small amount of additional space is important because it helps maintain airflow and allows the cover to fit comfortably.

It is also worth checking nearby skirting boards, door frames and furniture to ensure there is sufficient room for installation.

When deciding between two sizes, it is usually better to choose the slightly larger option.

Do Radiator Covers Affect Heat Output?

A properly designed radiator cover should have very little impact on the performance of your heating system.

Modern radiator covers are designed with front slats, side openings and top ventilation panels that allow warm air to circulate naturally around the room. Choosing the correct size helps maintain this airflow and ensures the radiator continues to heat the room efficiently.
